.7 '0 all whom it may concern:

Be it known that I, PRESTON CHARLES VEST, of the town of Kinderslcy, inthe Province of Saskatchewan, Canada, have invented certain new anduseful Improvements in Shockers, of which the following is thespecification.

The invention relates to improvements in shockers and one of the objectsof the invention is to rovide a machine which will accompany t eordinary binding machine and will receive the sheaves ejected from thedeck thereof, form them into a stook and deposit the formed stook firmlyimplanted on the ground.

A further object of the invention is to construct the shocker so that itcan be readily leveled to accommodate the adjustments which may berequired in the binder.

A further object of the invention is to construct a shocker having areceiver which receives the sheaves directly from the deck and formsthem into a shock having the center of the shock spread to present agood base and the heads rawn together and to mount the receivers that itcan be adjusted in respect to the deck to accommodate the varyinglengths of sheaves which may be ejected over the deck.

A further object of the invention is to construct a shocker wherein thesheaves, in the form of a stock, are carried back in order to keep thestock relatively stationary in respect to the round as the binder andstooker advance, sue arrangement overcoming any tendency for the stockto fall over when being deposited or after depositing.

A still further object o the invention is to construct a machine whereinthe stook is kept under control for a short interval of time after ithas been deposited and to construct a machine so that as the stock isbeing brought to the ground it is, while still held, forcibly shoveddown to firmly impinge the stock on the stubble and insure a good base.

A further object of the invention is to pro vide a machine arranged andconstructed so that the attendant on the binder can control the time ofdepositing the stock, thereby allowin him to select the position wherethe stock is to be drop ed.

A still further 0 ject of the invention is to provide a shocking machinewith traveling gripping jaws for controlling the formed stock and to fitthe jaws with automatically actuated teeth which pierce the stock andthereby allow of a lighter grip, so to speak,

to be taken bythe pending the stook.

With the above general objects and other IIllIlOl ob ects in view theinvention consists jaws while properly susessentially in the arrangementandconstruo tion of parts hereinafter more, particularly described andlater pointed .out in the appended claims, reference being had to theaccompanying drawings in which Figure 1 represents a side view of the ma2 chine in the sheaf receiving position.

ln describing my stooker I have only considered it necessary to showthose parts of the binding machine with which my stocking machine isimmediately associated, such parts comprising the deck 1 of the binderand the binde11 fran1e,2, the said frame being.

supported the usual way at the deck side on the customary master or bullwheel 3. 5 My machine is located at the deck side of the binder,,with ithe. sheaf receiver thereof position d so that the sheaves ejected inthe ordinary way from the binder deck will be passed directly into thesheaf receiver. Further'theishockr is piyotally connected was binder'fremein order to accommodate itself to any unevenness' in the fieldwith '1 whichithe machine-may have toicon'tend.

flFiReferring-"now 00* the" drawings kreprele-sents'the'maiti-freme ofthe shocking mavhinwwhjqheom rises a front cross beam 5 aninher'sitle-beanr Ganda'pair "of opposing parallel outer: side beams 7and 8 extending from the'main'=-beam'-and having their rearendsfas'tened together bya'connecting beam 9. This 'eoiistruetionprovides "a substan- -tially i 'e'ctangiilar outer framework for the QTmiiin di iving-whee'blbofthe shocker, which drivingfwheel is'a duplicateof the master wheel bfthe' bind'erpnd is mounted on the cross shaft 11which 'is adjiistably carried in "theside racks' 12and 13-presented -b Ythe frame members 7 and 8. I Im'connectiomwitH the shaft adjustment 1may state that 'th'e sliaftis provided with p'inions 14 operativelymounted in the racks andgisa fitted further a worm wheel 15 innev'end hfa shaft 17.

Ihave not considered it necessary to give 'a dtailedfiesription of therack and pinions'ilonthe mannerin which they are adjusted as thisstructure is the same as what is now -used'onai'bi'nder to adjust theframe in respect to the master wheel. The action is' simply"that-' 0 1?in turning the shaft 17 causesg thrdugh the worm and worm wheel, 1 1":the frame i to"c1in:ibor run down the racks and gradually effects theraising or lowering of the outer side ofthe shocker frame in res'p'eetto the"driv ing";wheel which carries it. Obviously with such anarrangement I I can level my shocker in respect to the round,

at an'ytime depending upon any lcve ing adjustment'which may be made inthe binding machine. Theinner'side' of the shocker main frame, which itwill be noticed is comparatively' speaking short, is connected at theinner side pivotally as indicated at 18 and 18" to the outer ends of apair of fixed arms 19 and 19' permanently secured to the deck side ofthe binder frame. 22 represents an outer trailing beam having the rearend thereof carried by a caster wheel 22- and the'forward end thereofswung from a. pivot bolt 22" carried by a bracket 22 permanently securedto the frame member .j 21 represents a trailing beam similar to that 22.and located at the opposite side 65 of the shocker frame and having therear :engagea-ble with-a worm 16 located at the end thereof carried by acaster wheel 21' and the forward end securedpiyzotally by means oia bolt21 to a bracket 21 secured to the inner beam 6 of the shocker frame andpositioned directly opposing the former bracket.

These trailing beams carry a-str-ucture inter described.

The main frame of the shocker carries an adjustable sheaf receiver whichis located opposing the deck and isconstructed in de- "tail asnowdescribedi 23 and 23 represents pair of upstanding posts in thepresent instance formed from angle iron which'postsha e their lower endspermanentlyse'cured to t'he frontbeam 5 of the shocker frame and to theposts I secure permanently a vertically disposed but slightly incliningbutting plate '24.

'lhea'ear ends of the side bars 28and 28 are connected'pivotally by meansoli stub shafts 3U .andi-ZO tothe upper ends of upstanding sway bars 31 and 31 pivotally mounted on'the rear end of the main framed, the bar 31 being swung irom acounter-shaft-32 mount ed in the side bars 7 and 8 and the bar 31" from:1 pivot bolt 32' extending into the iueam (5 in a location directlyopposite the counter shaft. The shaft 25 is extending to tlie'binderterminating in a location for'ootr venient manipulation"by the driverand is fitted with a swinging joint such as a universal'joint25" toallow of the adjustment'of the shocker: The side bars 28 and 28"ca1rythe sheaf receiver 33 which in realit is constructed' from a springplateof an'e ongated. double U-shape and having one end open and flaringand the other end closed. v

The detailed shape of the sheaf receiver is bestshown in Fig. 113 of thedrawings, where it will be seen that the two ends of the plate areoppositely flared as indicated at 33 and ZW- nd that the plate is so.bent that a U- shaped passage 33 is formed to receive the sheaves, thetwo arms, D and E, so to speak, of the passage being separated by adivider 3 The receiver is'permanently secured at the inner side to theinner side bar by bolts 35 and is permanently secured at the outer sideto the outer side bar by bolts 35'. The end 33 of the plate is desi nedto pass beneath the delivery end of tie deck and the flared end 33thereof rides freely in a location above the deck, so that the sheavesejectby manipulating the shaft 25.

The stub shafts 30 and 30* hercinheforc referred to form a drive for acarrier which :.is herein described in detail and which is alsopivotally swung from the stub shafts Thecarrier embodies as the moreimportant partsa pair-of side-guides-or runwaysBG-lzind 37, endlesschains 38 and 38' alldlpflllsl of pivoted jaws 39 and all), the

jaws being mounted to operate [awkwardly and forwardly on'the runwaysand to he (llli'efl in a particular way. by the endless chains.- Theside 'guides are identical in construction and each comprises a pair oflengthwise extending spaced angle irons 41 and 41 having their endssuitably fastened together by straps 42, the forward strapsbeing'pimtally' mounted on the stub shafts as best shownin Figs. Hand 12of the drawin sz Elhe rearmost ends of the side guides are connected bya cross bar 43. The outer ends bf :therunw'ays carry across shaftellmount- 'ed in the outer straps 4:2 and to the said cross sliaftl se'curepermanently a pair of chain wheels 45 and 45'Jaround which I pass theouter ends of the chains 38 and 38, the inner ends-of the 'chainsbeing'mounted on ch'ain whels'zilfi -ai1d46' located'on the stub shafts 30alndBOfi The chain wheel 46 is connected by means of a sleeve 47' to adriving chain wheel-47 mounted also on the stub shaft and drivenby-meansof a driving chain 48 from an under chain wheel 48 secured to the innerend of the counter shaft 32.

r "The: counter shaft is supplied with a .i'rce chain wheel 49 connectedby means of a drivin @cha'in 4:9 with the main chain wheel 50 of theshocker which chain wheel is pcrrn'anent-ly securedin any suitablemanner tothawhel 10. A normally disengaged clutch; indicated generallyby the reference numeral. '51. is supplied on the counter shaft tocouple the free wheel 49 to the counter shaft whendcsired and in orderto effort the driving of the counter shaft and the conseuent operationof the chains 38 and 38. i he clutch is controlled in a particular manher later described.

The rear ends of the runwa s are sus pended by means of a pair 0relatively strong coiled springs 52 and 53 having their upper endsattached to elevated hanger bars 54and 54 rigidl suspended in eachinstance by side stan ard 55 and 56 mounted on the trailing beams 21 and22. The runways carry similar opposing sliding blocks 57 andfiS whichsupport pivotally the ends of a cross spindle 59 on which the jaws 39and +0 herein before mentioned are mounted. The slidingblocks actuallyvcomprise inner and outer plates (30 and 60 connected together by crosspins 60 on which I mount suitably located rollers 60*, the rollersactually riding on the edges ofthe flanges of the angle irons formingthe side uides. This arrangement is best shown in *ig. 6 of thedrawings.

The inner plates of the blocks; carry 'in each instance a special catchmechanism for alternately connecting the blocks with the upperand lowersides of the chains 38 and 38 to eflect the forward and backslidingmovement of the blocks and consequently the jaws in the guides. Thecatch mechanism comprises (see Fig. 9) a-c omparatively short catch bar61 fitted at the ends with flllpOSltGlY arranged catches 61' and 61 andpii-olally suspended by top and bottom sets of swinging links 62 and62'pivotally-secured to the catch plate at 62* and to the inner plate 60 ofthe sliding block at 62 (33 and (34 represent a pair of levers pivotallysecured more or less centrally of their length to the plate 60 andhaving their inner ends connected together by a pivot pin (54' carriedby the lever 64 and opera-tin within a slot 63 located in the adjacenten of the lever 63. The outer end of the lever 64 is pivotally attachedto the catch plate by means of a pin 65 and a coiled spring fifi extendsbetween the pin 65 and a further pin 67 located at the free end of thelever 63. joint formed between the levers 63 and 64 with the result thatwhen the top catch 61' is struck down the spring holds the latter jointbuckled upwardly, as best shown in Fig. 5 of the drawings, and with thelower catch 61 in its lowermost position. In this connection it will beobvious that when the catches of the catch plate are struck either up ordown the links carrying the catch plate swing and this action results inthe buckling of the joint between the levers either upwardly ordownwardly as the case may be and the levers are held in the buckledposition by the action of the spring. The catch plate is designed sothat when (he catches are in the lowermost position the lower catch isprojected into one or other of the links of the underside of theadjoining chain and such that when, the catch plate is in the uppermostposition the upper catch is engaged within one or another of the linksoi the adjoining upper side of the chain.

By controlling the instant at which the catches are struck I can causethe sliding blocks to travel out the runways when the lower catches areengaged with the chains and back on the runway when the top catches areengaged with the top sides of the chains. l

This spring is designed to buckle the extending striker ba'rs'39 and40*.

T0 actuate the catches I employ inner and outertrips68 and 68' on therunways, the trips 68 being positioned adjoining the outer chain wheelsand those 68 adjoining the inner chain wheelsi Referring to Fig." 5 ofthe drawings, it will be seen that as the chain turns the sliding blockiscarried?toward the chain wheel 45 owingto the engagement of the lowercatch with a link of the chain and that as the sliding block-approachesthe chain wheel 45 the lower catch'is' struck by the trip 68 anddisengaged from the chain. As the lower trip :disen'gages thetop tripcatches into the top part of the chain'into one of the top linkswith-the resultthatxthe sliding block is caused to,travel intheyopposite direction with the chain. It will then continue travelinginwardly :until it strikes the outer trip .68 where the: action isreversedand the other trip engaged; The actiqnjustdescribed relativctothe sliding block-"shown in the said Fig. 5 is taking placesimultaneously 'in the other sliding bloc'lrso' that while I use whatmight bescalled a continuous chain drivethe blocks arereciprocatedoutwardly and inwardly on the innwaysa andicarry; with-themthe jaws 'or-- grippers hereinbefore referred to. The jaws appearinpairs at opposite sides of the runwa Ifand are connected bytransversely extending combination gripping and stripfilltfizrbltl 69and'69 permanently secured to 1 e tips of the jaws and have the arms 39and 40' thereof connected by transversely The tips of each "pair of jawsare fitted with sets of prongs 70aextending from cross shafts 70 whichhave their ends terminating in cranks pivotally secured at '70 to theends of the jaws and with the cranks fitted with short levers70 .To' thelevers I connect at each end -a set oflcross'links 71 and 72, the link71 being ivotally secured at 71' to the lower jaw, whi e the link 7 2 ispivotally secured at 42 to the top jaw. From this arrangement it will beobvious that as the jaws are closed together the links act to pro ectthe rongs beyond the combination stripping an gripping bars the rojectedposition being best shown in tone outline in Fig. 1 of the drawings. Thejaws at each side are connected by'a coiled spring 73 which normallyacts to draw the jaws together. The tip of each jaw carries a stop in 74which limits the swing of the levers (0 so that the links cannot passover dead center. In the operation of the machine I desire the jaws tobeswung around to what might be called the horizontal position and to beopened when they approach the sheaf receiver as they are utilized towithdraw the sheaves from the receiver and carry the same back in theform of a stock to the rear end of the runways at which point the stockis deposited. To accomplish the turning of the jaws to the horizontalposition and the opening of the same I locate upper and lower pairs ofspring pressed catches 7 5 and 76-, these catches being secured to therunways and each presenting an inclined flange 77 which has the inner orforward end thereof out off at an angle as indicated at 77' (see Fig.7); The catches are fastened to the runways by a number of pins 78operating in slots 78' which allow the catches to have an in and outmovement in respect to the an is bars carrying them and they are normaly held in the inner position by the action of a spring 79 passed aroundone of the pins and with its extremities bearing against the outer faceof the catch.

By stating that the flanges incline I mean that they are not'parallel tothe angle bars of the runways but converge toward them, being farthestaway from the runways at their outer ends and nearest the same at theirinner ends.

The exact position which these pairs of catches have on the runways isdetermined entirely by the timing of the catching of'the sheaves by thejaws as I wish the jaws, when coming in, to 'be first swung to theirhorizontal position by the top catches, then opened by the pairs ofcatches and retained open in position above and below the sheaves untilthe attendant is prepared to withdraw the sheaves in the form of a shockfrom the sheaf receiver. I

In considering the action of the jaws in respect to the catches and 7 6I might here state that the jaws are offset at 39 and 40 so that the jawarms at the opposite sides of the runway are farther apart than thegripping ends of the jaws with the result that" when the jaws orgrippers are comin in on the runways and in the vertical position asshown. in Fig. 2 of the drawings the then leading jaw arms will en agewith the rear ends of the flanges 77 o the top pair of catches whichwill have the effect of swinging the jaws over to bring them to thehorizontal position and in this swinging over action the gripping endsof the aws will swing clear of the flanges of the lower catches.

However, after the jaws have reached approximately their horizontalposition the then trailing gripping arms will be both caught by theflanges of the pairs of catches which will, owing to the inclination ofthe flanges, cause the jaws to be opened as the blocks continue movinginwardly. The release of the jaws occurs the instant the controllingends of the jaw arms are free to escape from the inner ends of theflanges 77. This release however in the present machine does not occuruntil the proper number of sheaves has been put into the sheaf receiverand then the machine is momcn' "this momentary tarily automatically. putinto action to clear the trailing ends of. the jaw arms, allow the jawsto close onthe assembled sheaves and withdraw the jaws with theassembled sheaves a predetermined distance on the runways after whichtime they are stopped. The positiontliey occupy when so stopped is shownin dotted outline inFig. 1.]

The device .for automatically controlling action, so to'speak, of thejaws is now described.- l 1 The butting plate24 isfitted at the lowerinner oornerwitli a vertically disposed pivoted lever 80 to the lowerend of which I secure-a rod 80, which passes across the front end of theshocker frame and is connectedto the extending end of a crank 81'carried by a lengthwise extending rod 81 suitably carried by the innerbar '7 of the shocker'frame. This latter rod is provided at the rearmostend with a crank 82 to which I connect a. shifting rod 83fitted with aspanner 84 which passes to the shifting member of the clutch 51. Aspiral spring 85 is connected to the lower end of the lever 80 andextends to a bracket 85' secured to the upright 23'. This spring-holdsthe le Yer normally in such a position that the clutch members aredisengaged.

At the front of the shocker frame I locate a cross rod 86'which isfitted with an upstanding, crank 86' connected byemeans of a short link8.7 to a bell crank-88 suitably supported from the beam 5'and' havingthe rear end thereof pivotallyattached at 88- to the cross rod 80. Therod 86 is continued over to the binder, there being a universal joint 86to accommodate the swinging ofthe machine and at the hinder the said rod.is fitted with a suitably positioned foot pedal 89 within convenientrange of the attendant.v 1

Considering the sheaves successively passed from the deck into the sheafreceiver it will be seen that they, will push one another into thereceiver until such a time that the receiver is filled and at this timethe innermost sheaf, or the one at the inner end of the passage 33 willbe engaging with the lever 80 and gradually forcing it in toward thebinder until it is forced far enou to efiect the engagement of theclutcli. The instant the clutch engages the jaws pass -.forward for ashort interval to allow the trailing ends of the arms thereof to escapethe catches and the instant this occurs the jaws grip the exposed headsof the sheaves and start back with the sheaves and continue travelingback until the sheavesare pulled'clear of the receiver. The instant theyare clear of the receiver the jaws with the stock naturally swing downto the vertical position and coincident with the escape of the sheavesfrom the receiver the lever 80 is liberated and the spring 86 acts topull back the lever and disenga the clutch'. This action occursveryiqulc yandv-during: the action the catch plates 6l-have also beenactuated and at the end oflthe action. the; jaws are in a positionapproximately as-;in-;-; dicated in dotted outline in Fig.1 of the'drawings. 1 a

Here they. remain inert suspending the stook..until the. attendant isprepared to; drop .it. W'hen ready he? resses the, footlever whichoperates throng the rod 86 and associated parts to againpthrowrin.--thc-. clutch and the clutch remains in .as longes-- his foot is onthe pedal with the resultthat; the jaws are carried backto' the rear endch the runways and forwardly againto stopping positionwhich occurs whenhe releases the foot pedal. In the back oroutgoingmovement of thejawsthe jaw arms strikew the flanges T7 of the catches but thecatchesfispring out to accommodate and allow them A to pass and then return totheir;.original set position. l; 1

As the jaws approach the outer ition on the runways they. are opened andtliis is;,90 accomplished in the presentinstance by: a jamming action onthe striker bars 39* and 40* .tig'hich isaccomplished by the followings;par 1 :l 5' I.

To the inner plates ofithe sliding bloeks so I secure permanently a pair(ifupstanding fingers A and, 3 which go with theblock'si; and occupy aposition to the one side ,of; thel striker bar =10", as the jawsapproach the'f: outer position (see F ig. 2) and prevent-. tlie--l00iarms 39 of the jaws from rotating in theoz direction indicated bythe-applied arrowu (Fig. 2). The other strikcr- 'har l0"; ofthe jaws isdesigned to engage with a stop bar Cw secured permanently to the crossbar 43:1:1052 Obviously as the jaws arepasse'd to thepo-ni sition shownin Fig. 2 the then leading striker: bar will hit the stop bar C and asthe o.ut-' '1" ward movement continues the jaw arms Wlllz? be drawntogether and the jaws opened to l 10:- deposit the stock. *1 j 1 Duringthis releasing of the jaws they: prongs are alsonutomatically and:quickly a withdrawn from the sheaves and the bars;

sheaves from the prongs. During the interval that the jaws'rarepassingbackwardly on the runways and ate. a time when they areapproaching'the rear, 7 end thereof I desire that the rear end of thecarrier be swung downwardlytoward the.1 0 ground to firmly implant orimpinge the base of the stool: on thoground and also desire to 'fquickly release the carrier after thestock-am. has been implanted toswing up clear of the stool: and have this movement occur the stant thejaws are released. For this-pur l; pose i provide what I have termedstook. setters 90 which comprise the parts now de-, scribed. To each ofthe rear standards 55 I secure 1- 0 69 and 69' strip the pivotally andadjustably rearwardly extendmg swinging arms 91, the rearmost ends ofwhich are sus ended from the carrier by comparativelyight coiled springs92. The joint formed between the standards and the arms is one whichallows ofthe forward and rear adjustment of the arms and of the swinginof thearms in respect to the standands an it comprises, in the r 16stance, a bolt 93 assed through t e standard and through as 6t 91'- inthe arm and provide'd with a pair of lock nuts 94 and 94 which areadapted to jam against the o os in "feces of the arm-after t standingtrip bar 95"which is adjustable in respect to the arm, this beingaccomplished by a tie :bar 96 extending between the trip 20 bit snacksarm and adjustably secured by in bodily shifted in the adju'stmeht ofthe si e bars '28 and 28""the inner ends of the arms 91 will move-withthe stubshafts.

(b-detain" with the trip bars I provide shoes-98", t ere being a shoeextending latera'll and outwardly front eaeli of'the sliding locks. Aswill be observed in Fig. 3 the inner ends (Sf-these shoes are tapered"at 98; y in order that inthe inward movementof the sliding blocks the"trip arms will be pressed-out and cleared past thesh'oes.

In order that the machine may be better understood I will now describethe manner in which it operates, assuming that the parts are intheposition as shown inFig. 1 of the drawings.

As thesheav'es are ej ected from the binder deck they pass into thereceiver between the flared ends thereof and as the receiver is formedfrom a spring plate they are caught and held by the receiver, thenatural tendency of the late being to open slightly so that the receivedsheaf is under slight pressure. Each successive 'sheaf'presses thepreceding sheaf farther into the passage 33 "until finally the passageis filled and the then leadingsheaf engages and actuates the lever 80.The instant the lever is in this way automatically swun the clutch isengaged and the jaws pass inwardly toward the receiver sufficiently farto clear the j aw resent inp 1e same hasb een 'a "usted to'the desiredposition.

'l he rear end ofeach"arm carries an uparms. firom the catchesatwhich'time the" jaws grab the sheavesand the' prongs are projectedinto the same. The mstant the sheaves are cleared from the receiver thesheaves in the form of a. stook fall down and swing the jaws to whatmiht be termed. their vertical position and with the butt of the shockentirely clear of the ground.

Coincident with the. .releasmg of the sheaves from the receiver. thelever-80is actuated by its sprin to disengage the clutch and the jawsare len stopped and remain inert and suspending the stool: until thedriver wishes to deposit the stock.

During the above action it 'will be under stood that the catchmechanisms have been actuated to ievetse the direction of movement ofthe sliding blocks;

When the attendant desires to deposit the stool; carried by the jaws hepresses the foot '85 lever to engage the clutch and immediately the jawsstart traveling'out on the carrier.

In goingout the catch plates are pressed back to allow of the passageof-the jaws and as the jaws approachthe trip bars of the stook settersthe shoes engage the upper ends 'of the trip bars and force them down,

the stook setters swinging on the bolts 93. This swinging down actionproduced in the stooklsetters as they engage primarily with the fOIWiildends of the slums andtheu later riding along the under face of the shoescauses the quick down pulling of the outer end of the runways,thisthroufii the springs 92 and the weight of the stoo ,sn'd the instantthat the upper ends of the trip hers clear off the inner ends of theshoes the carrier is quickly raised to the normal position by thesprings =32 and 53. Obviously this down action ofthe outer end ofthecar' rierforces the stock-to the ground, while still controlling it, andfirmly sets'or impingesthe base of the stock on the ground sothat itispreperly set. In fact the action is practically identical to the handaction employed when one, by hand, places a stock on the ground.

Just prior to the time that the upper ends of the trip bars-' clear theinner ends of the shoes the jaw arms are pressed together quickly by theaction of the stop bar 89 and the fingeis 87 and 88 and consequently thejaws are released and the prongs are withdrawn so that the stock isfreed from the machine at the instant the trip bars are cleared 'fromthe shoes;

During this entire back carrying and releasing movement of the stock theattendant has his foot on the pedal and after the steel: has beenimplanted he can,' when desired, release the foot pedal to throw theclutch out of engagment at which tiine the" jaws will stop traveling. y

This can occur at any time after the trip bars have cleared from theshoes.

.The above eomipletes the action' of deposit: his action is continuedas' ing the zstookii long aszthe machine is in use.
